Graphics w/Transparent Backgrounds

:roll: I'm a complete newbie and am trying to learn PureBasic. I've searched the forums but cannot find an answer (much less a simple one) that will tell me how to do the following ... please help:
I'm using the "Image Gadget" in the Visual Designer to get a graphic. If the image done in Photoshop has a transparent background, why wouldn't it in in designer?
What do I need to get rid of any background colors on images?
Many thanks to all in this great forum!
Kevin.

Hello, Gnome:
If you use a .png image or a .tiff image, alpha transparency will be displayed correctly when you use the command DrawAlphaImage() to display the graphic. You will have to use the appropriate decoder as well:
Code: Select all
UsePNGImageDecoder()
CatchImage(0, ?pic)
OpenWindow(0,0,0,320,240,#PB_Window_SystemMenu,"My Window")
StartDrawing(WindowOutput(0))
DrawAlphaImage(ImageID(0),0,0)
StopDrawing()
Repeat
EventID=WaitWindowEvent(1)
Until EventID=#PB_Event_CloseWindow
DataSection
pic: IncludeBinary "MyImage.png"
EndDataSection
afaik the ImageGadget doesn't manage alpha transparency for now (I think)

Thank you for your fantastic help ... I shall try it out as soon as possible!
May I ask what you mean by 'alpha transparency?'
And, say I use a .TIF or .PNG image ... what do I do with these graphics? (i.e., make a clipping path?, remove the background in Photoshop so that it's transparent?, save it any particular way?)
Thank you again for your most appreciated help!
Regards,
Kevin.

For those use 32-bit icons.
